Protein modification and maintenance systems as biomarkers of ageing [PDF]

open access: yes, 2015
Changes in the abundance and post-translational modification of proteins and accumulation of some covalently modified proteins have been proposed to represent hallmarks of biological ageing.

Functional divergence in the role of N-linked glycosylation in smoothened signaling [PDF]

open access: yes, 2015
The G protein-coupled receptor (GPCR) Smoothened (Smo) is the requisite signal transducer of the evolutionarily conserved Hedgehog (Hh) pathway. Although aspects of Smo signaling are conserved from Drosophila to vertebrates, significant differences have ...

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]

open access: yes, 2020
Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,

α-TubK40me3 is required for neuronal polarization and migration by promoting microtubule formation

open access: yesNature Communications, 2021
Post-translational modifications of tubulins regulate microtubule properties and neural development. Here, the authors report that one such post-translational modification, α-TubK40me3, is required for neuronal polarization and migration by promoting ...

Cardiac sodium channel palmitoylation regulates channel availability and myocyte excitability with implications for arrhythmia generation [PDF]

open access: yes, 2016
Cardiac voltage-gated sodium channels (Nav1.5) play an essential role in regulating cardiac electric activity by initiating and propagating action potentials in the heart.

Clathrin Heavy Chain Knockdown Impacts CXCR4 Signaling and Post-translational Modification

open access: yesFrontiers in Cell and Developmental Biology, 2019
Recent research has implicated endocytic pathways as important regulators of receptor signaling. However, the role of endocytosis in regulating chemokine CXC receptor 4 (CXCR4) signaling remains largely unknown.

Stage-specific histone modification profiles reveal global transitions in the Xenopus embryonic epigenome. [PDF]

open access: yes, 2011
Vertebrate embryos are derived from a transitory pool of pluripotent cells. By the process of embryonic induction, these precursor cells are assigned to specific fates and differentiation programs.

Evaluating Mechanisms of IDH1 Regulation through Site-Specific Acetylation Mimics

open access: yesBiomolecules, 2021
Isocitrate dehydrogenase (IDH1) catalyzes the reversible NADP+-dependent oxidation of isocitrate to α-ketoglutarate (αKG). IDH1 mutations, primarily R132H, drive > 80% of low-grade gliomas and secondary glioblastomas and facilitate the NADPH-dependent ...

On the existence of Hopf bifurcations in the sequential and distributive double phosphorylation cycle [PDF]

open access: yes, 2019
Protein phosphorylation cycles are important mechanisms of the post translational modification of a protein and as such an integral part of intracellular signaling and control. We consider the sequential phosphorylation and dephosphorylation of a protein
